I switched from a different userscript extension to Violentmonkey due to the fact that it's open-source, and the peace-of-mind that that offers (considering the permissions that are required to run this sort of extension).

The switch was trivial and all of my scripts worked flawlessly.

Highly recommend.

Restore trust to USER use of User Script. Better maintained. Better policy. Better people.

Lightweight, fast and open-source. The best userscript manager for Firefox.

Recently switched to Violentmonkey as it is a userscript extension that is open source and kept up to date. Working great so far with my existing userscripts I imported with the import feature. Had been using Greasemonkey until now but that hasn't been updated in 3 years so started to experience issues, and won't consider using Tampermonkey as it's closed source.

开源就是正义

与tempermonkey比兼容性稍有不足，但是开源且易用性更好
